Scientists at the U.S. Geological Survey are closely watching the long, thin barrier islands that comprise the Gulf of Mexico coast of west Florida as Hurricane Ivan approaches. These islands are particularly vulnerable to storm surge and coastal change during hurricanes because of their low elevation. New elevation maps show just how vulnerable.
“If Hurricane Ivan comes ashore on west Florida’s barrier islands as a major hurricane, Category 3 or stronger, most of the coast has the potential to be inundated by storm surge under the south eye wall at landfall,” said Abby Sallenger, a USGS oceanographer.
The USGS and NASA recently surveyed these islands using airborne laser mapping, providing for the first time detailed elevation maps of the island’s ‘first line of defense.’ An example of the ‘first line of defense’ would be a sand dune protecting an ocean front cottage or road. The average Florida west coast ‘first line of defense’ elevation is about 6 feet -- less than half the 13-foot average of the Florida east coast where Hurricane Frances made landfall a week ago.

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no. F91 in Hall 4.0.
They are united in their passion for OLED (organic light emitting diodes) lighting with all of its unique facets and application possibilities. Thus experts in...
A new scenario seeking to explain how Mars' putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million...
For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
